  In an essay titled Neural networks are already clean, Cammarata wrote We can now understand most neurons in models up to trillions of parameters and that the outlook for interpretability may be far better than I'd feared.

  The Goodfire researcher argues that early evidence for superposition and polysemantic neurons was misread, citing preliminary audits of Qwen3-32B in which about 90% of neurons have one main job. He ties it to safety: the building blocks that contribute to deceptive behavior by models probably have alignment-relevant microstructure.

  Details and sources

  He hedges heavily: samples are small and the cleanliness score is a rough pointer. The page is undated; Techmeme listed it on the afternoon of Oct 15.
